Description

Heptyl 4-(Dimethylamino)Benzoate is a specialized organic ester compound, widely recognized as a highly effective UV-A absorber and light stabilizer. Its primary value lies in its ability to protect materials from photodegradation, thereby extending their functional lifespan and maintaining their aesthetic and structural integrity. This product is essential for formulators and manufacturers in the cosmetics, personal care, plastics, and coatings industries who require reliable protection against ultraviolet radiation.

Application

• Sunscreen and Cosmetic Formulations: Acts as a primary or secondary UV-A filter in sunscreens, day creams, and makeup products to provide broad-spectrum protection.
• Polymer and Plastic Stabilization: Incorporated into polymers like PVC, polyolefins, and polyurethanes to prevent yellowing, embrittlement, and loss of mechanical properties caused by sunlight exposure.
• Protective Coatings and Paints: Used in automotive, industrial, and architectural coatings to enhance the weatherability and colorfastness of the finished surface.
• Hair Care Products: Protects hair colorants and styling products from UV-induced fading and damage.
• Adhesives and Sealants: Improves the long-term durability of adhesive bonds and sealants used in outdoor applications.
• Packaging Materials: Added to plastic films and containers to protect the packaged contents, such as food, pharmaceuticals, or sensitive chemicals, from UV light.

Quality Control

Our Heptyl 4-(Dimethylamino)Benzoate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. It is produced in compliance with relevant GMP and ISO 9001 guidelines. Every lot is subjected to rigorous analytical testing, including identity confirmation, purity assay, and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, the container should be opaque or stored in darkness to maintain product efficacy.
